LG Electronics 55LA86-Z 1. System

1. System

Remote

RF Receiver

UART

or USB

Pairing Information Transmission (Send to TV after Paired)

•Static Calibration Data (Bypass only)

•Remote FW ver. (Save also in Receiver)

•BD_ADDR (Save also in Receiver)

•Pairing Information Transmission Sequence

•When it is paired, the remote sends packets(pairing success, F/W version, BD_ADDR) to the receiver.

•The receiver sends the pairing success packet to TV directly.

•F/W version and BD_ADDR packets are just saved on the receiver.

•The receiver sends F/W version or BD_ADDR packet to TV when it is required.

Motion Data Transmission

•Period : 7.5msec

•Motion Data : gyro, accelerometer

Voice Data Transmission

•Period : 10msec

•Voice sampling : 16khz 16bit
